The tumors may be either benign (not cancer) or malignant (cancer): 1  Benign brain and spinal cord tumors grow and press on nearby areas of the brain. 2  They rarely spread into other tissues and may recur (come back).

Spinal cancer information Primary spinal cancer develops from cells within the spinal cord or from its surrounding structures (the bones, tissues, fluid or nerves of the spine). Part of the central nervous system (CNS), the spinal cord is a column of nerve tissue which extends from the base of the brain down the back.It is surrounded by three protective membranes and is enclosed within the vertebrae. The spinal cord carries important messages between the brain and the rest of the body.art of the central nervous system (CNS), the spinal cord is a column of nerve tissue which extends from the base of the brain down the back.

Adult Brain Tumors An adult central nervous system tumor is a disease in which abnormal cells form in the tissues of the brain and/or spinal cord. There are many types of brain and spinal cord tumors. The tumors are formed by the abnormal growth of cells and may begin in different parts of the brain or spinal cord.

Meningiomas Three layers of membranes, called meninges, lying just under the skull, protect the brain and spinal cord. From the outermost layer inward they are: the dura mater, arachnoid mater, and pia mater.A meningioma grows from the arachnoid cells that form the middle layer, and are firmly attached to the dura. meningioma is a type of tumor that grows from the protective membranes, called meninges, which surround the brain and spinal cord. Most meningiomas are benign (not cancerous) and slow growing; however, some can be malignant.

- Schwannomas are tumors of the tissue that covers the nerves (nerve sheath). These tumors develop from a type of cell called a Schwann cell, which gives these tumors their name. They are usually benign (not cancerous). Although schwannomas can arise from any nerve in the body, the most common areas include the nerves of the head and neck and those involved with moving the arms and legs.

What Are Adult Brain and Spinal Cord Tumors? Most brain and spinal cord tumors develop from glial cells. These tumors are sometimes referred to as gliomas. There are 3 types of glial cells – astrocytes, oligodendrocytes, and ependymal cells. A fourth cell type called microglia is part of the immune system and is not truly a glial cell.1  Astrocytes help support and nourish neurons. 2  When the brain is injured, astrocytes form scar tissue that helps repair the damage. 3  The main tumors starting in these cells are called astrocytomas or glioblastomas.ypes of cells and body tissues in the brain and spinal cord. The brain and spinal cord have many kinds of tissues and cells, which can develop into different types of tumors. Neurons (nerve cells): These are the most important cells in the brain.

Schwannomatosis Schwannomatosis is a disorder characterized by multiple noncancerous (benign) tumors called schwannomas, which are a type of tumor that grows on nerves. Schwannomas develop when Schwann cells, which are specialized cells that normally form an insulating layer around the nerve, grow uncontrollably to form a tumor.

Neuroblastoma 1 Neuroblastoma is a disease in which cancer cells form in nerve tissue of the adrenal gland, neck, chest, or spinal cord.  Neuroblastoma is the third most common childhood cancer after leukemias and cancer of the central nervous system.

Nervous tissue Neurons are cells with specialized features that allow them to receive and facilitate nerve impulses, or action potentials, across their membrane to the next neuron. They possess a large cell body (soma), with cell projections called dendrites and an axon.tructure [edit]. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Typically, nervous tissue is categorized into four types of tissue. In the central nervous system (CNS), the tissue types found are grey matter and white matter.

- Leiomyosarcoma is a malignant (cancerous) tumor that arises from smooth muscle Cells There are essentially two types of muscles in the body-voluntary and involuntary. Smooth muscles are involuntary muscles-the brain has no conscious control over them.t is very rare to see it in lymphatics. Since smooth muscle is found all over the body, a leiomyosarcoma can form almost anywhere where there are blood vessels, heart, liver, pancreas, genitourinary and gastrointestinal tract, the space behind the abdominal cavity (retroperitoneum), uterus, skin.

Sarcoma [edit on Wikidata] A sarcoma (from the Greek σάρξ sarx meaning flesh) is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancellous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma. Human sarcomas are quite rare.
